Modern computers are good at multitasking. Quad-core devices like the Pi 2 and 3 can share work between their cores, and your programs can run up to four times faster if you know how to code them in parallel. However, this is not always easy.
Programming languages like Python are sequential, executing instructions one at a time. What if you want to use all four cores? Luckily, there is help from the multiprocessing module, which allows parts of your program to run in parallel. To demonstrate how it works, we will adapt a program so that its central part runs in parallel, creating some beautiful fractal images in the process.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
